Our wisdom teeth are the third molars that usually emerge when we are in our late teens or early twenties. Not all people develop wisdom teeth. Genetic makeup means some populations and some individuals only have two molars. This is can be a blessing in disguise as wisdom teeth often cause problems when they do not emerge properly. This means have them extracted. Recently studies suggest there may be another reason why some do not develop these later adult teeth.
Aesthetic administered in childhood may prevent wisdom teeth from ever developing. Though the wisdom teeth do not emerge till much later they initially start forming in the jaw between the ages of 2 and 6. Some studies have suggested that children receiving aesthetic in the lower jaw around this age are less likely to develop wisdom teeth when they are older. The pattern, which is still speculative, has previous gone unnoticed due to the long time between the administrated aesthetic and the resulting lack of tooth development several years later. Statistics do show a pattern, but the cause is still under discussion.
As many wisdom teeth are causing problems this discovery may lead to a procedure that prevents them from every forming. We usually do not need these extra teeth, and often have to have the removed. A simple injection that prevents the problem from ever occurring might be welcomed.
